UNITED STATES PATENT OFFICE,

ALEXANDER GEMMELL AND ALEXANDER BOYD, OF TORONTO, ONTARIO, CANADA.

BOOT AND SHOE.

SPECIFICATION formingpart of Letters Patent No. 233,148, dated October 12, 1880.

Application filed August 17, 1880. (No model.)

To all whom it may concern:

Be it known that we, ALEXANDER GEM- MELL, manufacturer of boots and shoes, and ALEXANDER BOYD, merchant, both of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have jointly invented a certain new and useful Improvement in Boots and Shoes, of which the following is a specification. 7 The object of the invention is to utilize the movement of the foot for the purpose of ventilating the boot and it consists in perforating the quarters of the boot on opposite sides thereof over the shank, and inserting in said 1 perforations eyelets of a peculiar construction as hereinafter more fully set forth.

Figure 1 is a side view of our ventilated boot. Fig. 2 is a cross-section through a b Fig. 3, clip for protecting perforation.

In our improved system of Ventilation we perforate the quarters A on opposite sides, immediately over the shank, thereby admitting air between the arch of the foot and sole B of the boot, utilizing the upward and downward movement of the foot for the purpose of drawing in and propelling out the air, a portion being propelled around the foot, the motion of which, as stated, performing the duty of an airpump.

In order to secure the desired effect it is absolutely necessary that the holes should be situated exactly in the position stated-via, through both sides of the quarters, between the sole and arch of the foot, below the in- 3 5 step. Afresh current of air is thereby maintained around the foot.

0 represents a metallic eyelet of peculiar construction, designed to be inserted in one of the perforations made in the shoe above its shank. The eyelet G is provided with a cen- 4o tral orifice, b, and radial arms (IV a. The central portion of the eyelet is inserted in one of the perforations made in the shoe above its shank, and the ends 0 of the radial arms are passed through perforations made in the shoe, and are then bent inwardly down over the inner face of the leather to secure the metallic eyelet in place. By this construction the perforations in the shoe are prevented from being closed.

We are aware that perforations have been heretofore made in the uppers of shoes with valves applied thereto to secure ventilation, and we therefore lay no claim to such construction, our invention being confined to the application to such perforations of the eyelet of the peculiar construction heretofore described.

What we claim as our invention is- The combination, with a shoe having perfo- 6o rations in its quarters on opposite sides and over the shank, as set forth, of the eyelets 0, each having a central orifice, b, and radial arms a, the endsc of which are adapted to be inserted in perforations in the shoe and bent inwardly along. the inner face of the leather, substantially as described.
